This was inevitable. AdMob founder and CEO Omar Hamoui has responded to Apple blocking AdMob from the iOS ecosystem. Unsurprisingly, Hamoui isn't particularly amused, claiming that not only is it bad for competition, it will also hurt developers and users alike.

Is not fair because apple didnt make the app where the adv is gonna be shown.. if apple come with a portal that use google search, they can put their adv there.. no harm done.
If apple wants to use his adv plataform on their apps, ok.. but if any developers want to use admob, they should be able.. apple is taking away the choice of devs choosing their adv revenue.

Apple has been taking choice from devs.. first the language, now the adv.. next? the ownership of the app?

I want a plug-in system for Google Search where I can choose my favorite ad provider!
Not offering that is obviously abuse of Google's search monopoly to drive ad monopoly just like when MS bundled IE without offering alternatives!
